  • Patent number: 9202902
    Abstract: A semiconductor element encompasses a charge-transfer path defined in a semiconductor region (34.35), configured to transfer signal charges, (b) a pair of first field-control electrodes (42a, 42b) laminated via an insulating film on the semiconductor region so as to sandwich the charge-transfer path in between, and a pair of second field-control electrodes (43a, 43b) arranged separately from and adjacently to the first field-control electrodes (42a, 42b). By applying field-control voltages differing from each other, to the first and second field-control electrodes (43a, 43b), a depleted potential in the charge-transfer path is changed, and a movement of the signal charges transferring in the semiconductor region is controlled. Because electric field can be made constant over a long distance along the charge-transfer direction, a semiconductor element and a solid-state imaging device, in which problems caused by interface defects and the like are avoided, can be provided.

  • Patent number: 9182215
    Abstract: A strain sensor includes a flexible substrate, a CNT film made of a plurality of CNT fibers aligned in an orientation direction, a pair of electrodes, and a protective coat. The electrodes are formed at the opposite ends of the CNT film in a perpendicular direction to the orientation direction of the CNT fibers. The protective coat protecting the CNT film is made of a resin, a water-based emulsion, or an oil-based emulsion. The protective coat is placed in contact with at least part of the CTN fibers on the surface of the CNT film. The strain sensor including the protective coat is able to prevent damage/breakage of the CNT film and to prevent foreign matters from entering into gaps between CNT fibers, thus improving durability in maintaining adequate sensing functionality.

  • Patent number: 9118331
    Abstract: A contact state detection apparatus which can accurately detect the pressed state of a contact body such as a probe against an object without damaging the contact body or the object includes a contact body approach section, a probe light source, an imaging device, and a computer unit. The contact body approach section holds a contact body in an inclined attitude with respect to a target contact surface of an object, and displaces the contact body toward the object. The probe light source irradiates light toward the contact body which is being displaced toward the object. The imaging device captures an image of the illuminated contact body and outputs contact body captured image information to the computer unit. The computer unit detects the state of the contact body being pressed against the object based on a change in the contact body captured image information.

The boundary line of an adjacent region B is multiplexed outward, and an overlapped region D is provided between the initial region and the adjacent region, and a region X to be processed is projected onto a two-dimensional plane and a texture GB is allocated. An optimal boundary line FS in which the difference between the pixel values of the textures GA and GB becomes minimal in the overlapped region is obtained, and the texture GB is mapped in the region X being processed so that the texture is connected to the texture GA at the optimal boundary line. The apexes of the polygon mesh displaced on the basis of the textures mapped in all the regions are connected to obtain grain-given polygon data.
